Maybe it's just me, but I think he's asking if there is a typo in the code. He can't tell the difference between a redeemed code and a broken code.
If it has been redeemed, it will say 'this prepaid card has been spent'.
If it is broken, OR expired, OR a code for a different region, then it will say 'sorry this code does not appear to be valid' (or something like that, I am paraphrasing.)
There is no way to tell the difference in the invalid codes, unless someone knows the expiration and also knows the region.
